Comparison of yield response: Growers standard practice strips (GSP vs Alt GSP)

Ideally the yield would be the same in both strips (GSP and Alt GSP), and / or the yield would not be significantly different.

Significant yield differences between the two strips suggest that there is a high degree of variability between the two strip that were applied with the same fertiliser.

This may occur because the strips have underlying soil, plant growth conditions.

Comparison of yield response: High medium and low fertiliser rates

Different comparisons are made between high, medium and low fertiliser rates for each zone.

Comparison of yield response in the strip / zone per paddock between:

T- test was also run for each comparison and the significant differences at p < 0.05 reported. Note that some significant values are not reported for the zone, this may occur when there is not enough data points to run the t - test (although there is still have yield values to make a comparison).

The below table shows what fertiliser rates were assigned to low medium and high fertiliser rates.

Comparison of yield response: the growers fertilisers rate of application vs. higher or lower fertilisers rates.

Different comparisons are made between the growers standard practice and fertilisers strips for each zone.

Comparison of yield response in the strip / zone per paddock between:

The yield response is classed as ‘positive’ when higher rates of fertiliser results in higher yields

The yield response is classed as ‘no response’ when higher rates of fertiliser results in no change in yields (this is defined as 0 +/- standard error)

The yield response is classed as ‘negative’ when higher rates of fertiliser results in lower yields.

T- test was also run for each comparison and the significant differences at p < 0.05 reported. Note that some significant values are not reported for the zone, this may occur when there is not enough data points to run the t - test (although there is still have yield values to make a comparison).

The below table details what rates were excluded from the analysis. For sites with more than 3 rates one strip rate was exuded from the analysis.

If this should be a different rate and not the one excluded the analysis will need to be re - run. Please make a note.

Action required :

  1. Review that the results look sensible and nothing needs re running - are the reports OK to send off?

  2. The fertiliser applied has translated correctly to units of N or P.

  3. Are the rates included in the comparison analysis sensible and what you want.

  4. Are the paddocks to be included in the economics analysis?

Notes should be made in the below file:
